Those are awesome
Headliner, I've put them in...used fabric from Joanne's that my daughter picked out and we cleaned off the original headliner, scraped it to remove all the old fuzz, then sprayed, stretched and laid it down...felt pretty good about it, but there were definitely areas that could have stuck better.
Using the original material, whoa - nightmare! Why did you go that route vs just putting on new stuff and cutting the holes?
